The waterbomb actuator: a new origami-based pneumatic soft muscle
Bogunyà Piferrer, Victor
This project introduces a new Pneumatic Artificial Muscle (PAM) design based on an origami structure. This artificial muscle is designed to operate at a very low range of pressures while being lightweight and compliant. It is also designed to reduce the pressure threshold and hysteresis problems present on other PAMs like the McKibben actuator. These properties are achieved thanks to a rearranging membrane based on the Waterbomb pattern, which can contract upon inflation while keeping the surface area constant.
This concept has been tested using paper prototypes coated with silicone. We created thee different structures (4x8, 6x12 and 8x16 cells waterbomb actuators) from the same paper sheet (14x28cm2) and we actuated them under loads of 2, 4 and 7N. The 4x8 was discarded, but the 6x12 and 8x16 actuators contracted a maximum of 12.5% of the original length (≃10cm) while the operating pressures remained under 5Pa.
We also proposed a novel approach to 3D print these actuators using a Stratasys Objet260 Connex3 3D printer. The main idea consists in creating a flat structure that can self-assemble using a technique known as 4D Printing. The pattern is printed as a flat sheet where the hinges are composites composed of an elastomeric material and shape memory polymer (SMP) fibers. These hinges can be activated through a thermomechanical process inducing a self-folding effect.
Unfortunately, we were not able to verify this fabrication process due to the lack of material availability.

The objective of this master thesis is to calculate a five-risk factor model for the European stock market by replicating Fama and French (2015). Consistent with Fama and French (2015) results, this research shows that value, profitability and investment risk factors play an important role in assessing the expected return of an asset. These results shed light on the relation between the risk factors in North America and the risk factors in Europe.

Scaling-up a resource efficient economy: embedding biorefineries in the industry of the future through agile supply chains
de Regás Peña, Pablo
During recent years the design of industry supply chain has experimented significant changes through the establishment of collaborative networks. Nowadays, there is a strong necessity for reducing costs and offering the maximum agility in terms of product availability and rapid respond in front of unanticipated changes, facts that are being achieved by implementing decentralized supply chain structures.
Making reference to the article field of study, the biorefineries supply chain, some of their inefficiencies may be solved by adapting them to decentralised superstructures. Nevertheless, regarding the chemical and energy industry, these new guidelines in supply chain design are not yet full established due to the complications that may appear in terms of storage and transportation of intermediate products. There is a large amount of literature working on the objective to manage uncertainty in the biomass supply chain (Yue et al., 2014). As a concise summary, the main problems to face along the biomass supply chain consist on feedstock uncertainty, quality variability, demand variability, time dependence, storage, transportation and flexibility (Miret et al., 2016).
The aim of this document is to evaluate different feasible decentralized supply chain scenarios for the particular case of biorefineries, focusing on bio-ethanol production. The new scenarios are defined to struggle against the mentioned problems and provide more agility to the biomass supply chain.
The article will continue by introducing the current biorefinery concept, in order to define a starting point for the development of new scenarios. Next, a research on the state of the art of decentralised biorefineries will be presented. Right after, the KPIs selected to evaluate the advantages and disadvantages of the different scenarios will be introduced. Finally, a discussion of each scenario will be conducted for taking out the conclusions.

Avaluació dels pesos moleculars de la cel·lulosa
Garcia Cueto, Julia
L’objectiu principal d’aquest projecte és avaluar els pesos moleculars de la cel·lulosa.
Per assolir l’objectiu ha estat necessària una introducció teòrica prèvia sobre aspectes relacionats amb la cel·lulosa, com és el cas dels diversos orígens, de les seves propietats, dels diferents tipus de pesos moleculars dels polímers i de les tècniques existents per avaluar-los.
Seguidament, mitjançant una recerca bibliogràfica, s’explica amb detall els procediments que s’han fet servir per a dissoldre la cel·lulosa a partir de diversos dissolvents. Aquí es poden trobar les condicions de dissolució, el temps necessari, les quantitats de cada reactiu i un resum indicant els tipus de cel·lulosa que s’ha aconseguit dissoldre amb cadascun dels dissolvents utilitzats.
Els mètodes que han permès avaluar els pesos moleculars en aquest projecte han estat dos: la viscositat i la cromatografia GPC. De cadascun d’ells hi ha una introducció teòrica i, posteriorment, s’especifiquen els passos seguits per a dur a terme ambdues avaluacions.
A continuació es mostra un seguit de resultats. Primerament, es troben els espectres d’infraroig i de raig X que permeten caracteritzar tots els tipus de cel·lulosa que s’han utilitzat al llarg del projecte. Seguidament, es menciona quin és el millor dissolvent per dissoldre la cel·lulosa d’entre els utilitzats que, en aquest cas, ha estat el tartrat sòdic de ferro. Finalment, s’exposen els valors de pes molecular (en número, en pes i viscosimètric) de les cel·luloses obtinguts mitjançant viscositat i cromatografia GPC. En general, es pot dir que el pes molecular que s’ha obtingut del cotó és d’aproximadament 1.000.000 g/molt, mentre que el de la cel·lulosa industrial es troba al voltant de 300.000 g/mol.
S’ha fet també un estudi econòmic i un estudi sobre l’impacte ambiental que provoca la realització de la part experimental del projecte.
El treball conclou amb l’assoliment dels objectius: avaluar els pesos moleculars de la cel·lulosa a partir de diverses tècniques, passant per l’estudi de dissolució del polímer en qüestió.

Design and construction of a new, adaptable, test bed mounting system for an internal, combustion engine
Amarki, Jamal; Da Silva, João Nuno; Pornet, Adrian; Pantelimon, Bogdan
An engine test bed is a device which allows measurements on engines by making them run in a static way, which means that there is no need to use the vehicle for which the motor was made. Test beds are used in research and development departments of motor manufacturers, in order to ensure the design and the operation of prototypes before they are placed on the market. Hence, several parameters like capacity, performance, efficiency and other physical and chemical characteristics are reviewed. Reliability is also an important aspect of the development process and very specific parts of the engine can be tested for this purpose. Test beds are used for every kind of engines: diesel, gasoline, marine, agricultural, truck or car engines.
In the framework of the European Project Semester 2016 in the Polytechnic University of Bucharest, we had to work on the design and the construction of a new test bed adaptable mounting system for an internal combustion engine on the engine test bench of the Polytechnic University. The objective of our project was to make some alterations to the engine test bed on the engine mounting system in order to increase the flexibility of its use by making the engine switching easier and faster. We had to work with AKKA Company, in Dacia factory, on industrial engine test bed, to get inspired about the design, but also to test the mechanical comportment of it.
Our work has been divided in three steps. First, general researches about engine test bed and the different mounting systems existing. Then, we carried out measures and draws on CATIA of the existing mounting system of the university test bench, in order to make a static simulation to check the design in terms of mechanical resistance and bending. Finally, the last task consisted in doing exactly the same work as the second one, but on the test bed in Dacia plant.
The report of our work during this semester will be approached through three parts, corresponding to the three steps previously explained: researches on engine test bench, university test bed study and Dacia test bed study.
